Understanding the automatic obstruction-sensing feature.
Your garage door operator has an automatic safety feature built in, obstruction sensing. Knowing and
understanding how this feature works will help you maintain a safe and working automation system. This
feature monitors for any excessive physical resistance to the door while moving. Most often this resistance is
caused by badly maintained or un-balance doors. An untreated wooden door will travel differently in the
rainy season as it soaks up water and becomes heavier. Extreme weather conditions can also be a cause of
excessive physical resistance. A fiberglass door in a storm for instance. The obstruction sensing primarily
designed into your unit as a safety feature, (A door closing onto a motor vehicle) also protects the unit from
internal damage. Please test for the following on a regular basis or have your service provider do the tests.
Your door when sensing an obstruction;
ƒ
On opening should stop and wait for the next door-control trigger to reverse.
ƒ
On closing should stop and reverse to the open position. (For your safety, use a brick or milk crate to
test this.)
